VENTILATIN'G DEVICE.

Specification of Letters Patent.

Application filed September 10, 1913. Serial No. 789,089.

To all whom it may concern:

Be it known that I, MARY ETHOMPsON, a citizen of the United States, residing .at Newark, in the county of Essex and State of .New Jersey, have invented certain new and useful Improvements in Ventilating Devices; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to ventilating devices capable of a wide range of use, and has for its object to produce an apparatus which would be simple and certain inoperation, comparatively inexpensive to manufacture, and one that while permittinga free ventilation of the air will also exclude 111111.

. Withthese and other objects .in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter described and particularly ing or cellar; Fig. 4 is a detail diagrammatic View of a modified means of lifting my ventilator and Fig. 5 is an enlarged detail view showinga fusible connection in the operating chain.

1 indicates the frame of a sky light, vault or other inclosure it is desired to ventilate, and 2 a ledge or rim adapted to receive the packing 3 of the frame 1 0f the sky light or other cover. This frame when used for a sky light is provided with the glass members 5, of which there may be. any desired number, and 6 represents intermediate supporting pieces for the said glass. In order to secure the glass in place I provide on the frame, the holding members 7 whichmay be secured in place by the screws or other means 8, and I further provide the packing.

or other material 9 carried by said frame 4. The frame 4 is also provided with a groove or trough for collecting and draining off, by means of the drainage holes 61, any wa- Patented Oct. 27, 1914.

ter which may condense upon the under side l of the glass members 5. In like manner each of the membersG may beprovided with glass holders 10 and packing material 11 as shown.

To a plurality of thesup ortingqcross pieces 6 I secure the T-shapec hinge memhere 12 and secure thereto by the pins or bolts 13, the upper ends 14 of the lifting rods 15, eachsliding in the guides 16, and

provided with the rack teeth 17 meshing.

with the teeth of an idler 18, meshing with a pinion 20, rigid with the lever 21, and controlled by the chain or cords 22. The said chain connection 22 passes over the pulley.

23 carried by a support in the inclosure to be ventilated, thence over a secured pulley 24., and may pass over still a third pulley 25 if desired, whence it leads to any desired point not, shown whenit may be secured or manipulated at will, all as will be clear. p

from Fig" 1. i

It is obvious from the mechanism so far disclosed thatif one pulls on the chain con:

nection 22,. the levers 21. will be moved toward the glass, the idlers 20 willbe turned in opposite directions seenin Fig.1, the pin ions 18 will be turned alsoin opposite directions, the racks 17 will be moved upwardly, and thewhole framel and glass panes 5, moved from their full line positions to po sitions indicated by the dotted lines insaid Fig. 1. When the frame l is thus raised it is evident that there will be a free circulation of: air through the opening thus produced,while rain willbe excluded.

In the modified form of construction shown in Fig. 3, 35 represents a vault light, cellar door or other cover, 36 a frame work in all respects the same or similar to the frame 1 or otherwise constructed, 37 a drain;

for dew water or other material which may find its way on to the frame 36, 38 a lever directly attached to the pinion 18 and 39 a cord or chainconnection leading from the a lever 38 to the pulley 40. The other parts illustrated in sa1d figure are, or may be the same as in Fig. 1. It will likewise be apparent that should one pull upon the chain or cord connection 39 at the operating point.

not illustrated, the said levers 38 will be moved downwardly as seen in Fig.3, and

through the inions 18 the racks 17 and lifting rods 15 t e frame 31 will be moved from its full line .110 positionto its dotted line position shown in said figure, whereupon the.

tion of air is had through thespace 42," while rain is excluded. During this motion 1 the pipe 37 which has atelescopingcon nection with its guide 43 moves up with the frame 36, but is stilladapted to deliver" water into said guide 43 which may be drained off by means of a pipe 44.

In both of the forms of my invention I prefer to provide a fusible link 45 or other automatic means for operating the ventilator to a closed position should a fire break out; This said fusible link may be placed at any convenient point in-the chain connection 22 or 39-, and I have illustrated it for convenience only as being located near the'pulleys 24 and 40. It is shown in detail in Fig! 5 wherein the connection is illustratedas a chain, and its construction is as follows: One member of the chain is provi'ded with aring '46 and another member of said chain is provided with another ring 47 which is too large to pass through the ring 46. The two members of the chain are connectedas illustrated; by-the fusible link 45, and it'results from this construction that when the link is melted under the operation of a rise of temperature the two members of the chain 39 or 22 as the case may be, will slide over each otheruntil the two rings 46 and. i 47 contact, whereupon the chain will not lengthen any further. In the meantime should the frame work 4 illustratedin Fig. 1 be open as indicated in dotted lines and thefusible link 45 broken, it-is evident that the parts will descend by gravity into their full line positions, whereupon the ventilator will be closed. On the other hand should it bede'sired to counterbalance the frame work 4 I may add'to the lifting rods 15 the weigh te'dlevers 50, which tend constantly to open the ventilator, but the weights 51 of which are so adjusted as to notquite overpower the weight of-the frame 4 and its associated parts. Theseweights 51 render the operation of my sky-light easy. In the same Way should it be desired to counterbalance the Weight of the frame 36', a device precisely'the same or similar as that illustrated in Fig. 4 maybe associated with the lifting rods 15', so as to slightly overpower the 7 weight of the frame Work 36 and to constantlybring the said frame 36 into its dot tedlineposition. In such case the fusing of Copies of the; patent may be obtained for five centseach, by addressing the Commissioner of Patents,v

But when the said frame'35 is in the link 45 would effect the automatic closure of the said-frame- 36.

It is understood that the foregoing illustrations-and disclosures are merely examples of two embodiments of my invention, and that I am not to be restricted to the said disclosure except as may be required. by the claims, for'it is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of my invention:

What I claimis 1. In-"a ventilating apparatus the combination of a cover; a-seat for said cover; a plurality of supporting racks for said cover a pinion engaging each rack; a'second pinion engagingeach first named pinion; a lever associated' with eachsecond pinion for moving said. racks and cover'up' and down; and meanseomp'rising a flexible connection for controlling said levers, racks and pin ions at a' single point, substantially as described.

2'. In a ventilating apparatus, the combination of a transparent cover; a seat for said cover; a plurality of racks for supporting said cover; a pinion for engaging each rack; a lever provided with a second pinion for engaging each first named pinion; a flexible connection associated with-each leve'r; pulleys for guiding said flexible connection and guides for said racks causing. the same tomove saidv cover in a-vertical direction, whereby a free eirculation 'ofair may be had, substantiallyas described:

3. In'aaventilating apparatusthe combination'of a combined ventilator and-skylight comprising'a transparent cover; a seat for sai dcover; a plurality of racks for supportingsaid covei'"; a pinion for engaging each rack; a lever carrying a second pin-ion for engaging each rack engaging pinion; a

flexible connection associated with each lever provided with two members slidable with relation to each other and adapted to receive a fusible member; andpulleys for guiding said flexible connection, substantially as described.

In testimony whereof I aiiix my signa' ture, in presence of two witnesses.
